Abstract
Abstract An electrical connector (20) for mounting to a printed circuit board (24) includes a boardlock (22) secured thereto by an interference fit. The boardlock (22) has a first portion (58) including means for securing the boardlock (22) to the connector housing (26) and a second portion (68). The second portion (68) comprises spring means (72,74) extending from the first portion (58) to an end (80) beyond the mounting face (30) for reception in a boardlock receiving aperture (56) in the printed circuit board (24). The spring means (72,74) have a slot (70) therebetween and barb means (84) thereon with the barb means (84) positioned along the spring means (72,74) between the first portion (58) and the end (80) to engage wall means (92) of the boardlock receiving aperture (56).

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
104 words
An electrical connector for mounting to a printed circuit board, comprising: a dielectric housing having a boardlock receiving recess and a mounting face; a boardlock disposed in said recess, said boardlock having a first portion received in said recess in an interference fit, said boardlock having a second portion comprising spring means extending from said first portion to an end beyond said mounting face for reception in a boardlock receiving aperture in the printed circuit board, said spring means having barb means thereon positioned along the spring means between the first portion and the end to engage wall means of the boardlock receiving aperture.
Claim 2
Dependent Claim
104 words
An electrical connector for mounting to a printed circuit board, comprising: a dielectric housing having a boardlock receiving recess and a mounting face; a boardlock disposed in said recess, said boardlock having a first portion received in said recess in an interference fit, said boardlock having a second portion comprising spring means extending from said first portion to an end beyond said mounting face for reception in a boardlock receiving aperture in the printed circuit board, said spring means having barb means thereon positioned along the spring means between the first portion and the end to engage wall means of the boardlock receiving aperture.
Claim 3
Dependent Claim
21 words
An electrical connector as recited in claim 1 further comprising a first integral flange, said boardlock receiving recess in said flange.
Claim 4
Dependent Claim
39 words
An electrical connector as recited in claim 2 wherein said first integral flange further comprises a holding face opposed to said mounting face, and said recess is an aperture that extends between said mounting face and said holding face.
Claim 5
Dependent Claim
46 words
An electrical connector as recited in claim 3 further comprising a second flange integral with said housing, said second flange having a mounting face coplanar with the mounting face of the first flange, said second flange having an aperture therethrough with a like boardlock received therein.
Claim 6
Dependent Claim
14 words
An electrical connector as recited in claim 4 wherein the boardlocks are substantially planar.
Claim 7
Dependent Claim
16 words
An electrical connector as recited in claim 5 wherein the plane of the boardlocks are perpendicular.
Claim 8
Dependent Claim
34 words
An electrical connector as recited in claim 6 wherein the plane of the boardlocks are each at a 45 degree angle with respect to a line segment drawn through the axis of the apertures.
Claim 9
Dependent Claim
25 words
An electrical connector as recited in claim 1 wherein said boardlock receiving recess is a lateral channel extending into said housing from a side thereof.
Claim 10
Dependent Claim
37 words
An electrical connector as recited in claim 1 wherein the barb means are adapted to engage wall means of the boardlock receiving aperture in an interference fit upon mounting the electrical connector on the printed circuit board.
Claim 11
Dependent Claim
23 words
An electrical connector as recited in claim wherein the spring means comprise a pair of springs, said springs defining an elongate slot therebetween.
Claim 12
Dependent Claim
63 words
An electrical connector as recited in claim 10 further comprising means for actuating said spring means to spread said spring means, whereby upon mounting the electrical connector to a printed circuit board and actuating the spring means actuating means, the barb means engage wall means of the boardlock receiving aperture in an interference fit to secure the connector to the printed circuit board.
Claim 13
Dependent Claim
99 words
An electrical connector as recited in claim 10 wherein said elongate slot has a wider region proximate said first portion and a narrower region proximate the end, said boardlock further comprising an activating clip having spreading means thereon, said spreading means received in said wider region and adapted to be moved toward said narrower region whereby, upon mounting the electrical connector to a printed circuit board and moving the activating clip, the barb means on the spring means engage wall means of the boardlock receiving aperture in an interference fit to secure the connector to the printed circuit board.
Claim 14
Dependent Claim
35 words
An electrical connector as recited in claim 1 wherein the recess comprises a pair of spaced channels defining pairs of closely spaced opposed stop surfaces, said pair of spaced channels recessed from the mounting face.
Claim 15
Dependent Claim
68 words
An electrical connector as recited in claim 13 wherein said first portion comprises a clip insertable into said recess extending between said pair of spaced channels, said clip having a pair of side edges dimensioned to be received in said pair of spaced channels and moveable therealong during insertion, the side edges of said clip being received between the opposed stop surfaces of said pair of spaced channels.
Claim 16
Dependent Claim
18 words
An electrical connector as recited in claim 1 wherein the recess comprises a lateral channel in said housing.
Claim 17
Dependent Claim
78 words
An electrical connector as recited in claim 15 wherein said first portion comprises a sheared line segment with a region of said first portion adjacent said line segment formed out of the plane of the first portion to define a holding surface facing the end of said boardlock, said lateral channel having an offset facing away from said mounting face, said holding surface engaging said offset in the lateral channel to secure said boardlock in said lateral channel.
Claim 18
Dependent Claim
18 words
An electrical connector as recited in claim 1 wherein the recess comprises at least one contact receiving passage.
Claim 19
Dependent Claim
47 words
An electrical connector as recited in claim 17 further comprising a tab extending from the first portion, said tab having a barb thereon, said tab extending into a contact receiving passage with said barb engaging a wall of the passage to secure said boardlock to said housing.
